Multidisciplinary analysis of clinical cases: a transition towards active learning in dental education

In the past 2009/10 academic year, we took steps towards introduction of active methodologies, from a multidisciplinar approach, into a conventional lecture-based Dental Education program. We consolidated these practices in the current 2010/11 year, already within a new Bologna-adapted scheme. Transition involved (i) critical assessment of the limitations of traditional teaching (ii) identification of specific learning topics allowing for integration of contents, (iii) implementation of student-centred learning activities in old curricular plans (iv) assessment of students' satisfaction and perceived learning outcomes, (v) implementation of these changes in new Bologna-adapted curricula

Vida i obra de Fra Bernat Hug de Rocabertí

Fra Bernat Hug de Rocabertí (c.1420-1485) was a prominent member of the Order of the Hospital in the Crown of Aragon in which to attain the dignity of Castilian of Amposta, the most important dignity in the Crown. This work is a historical biography of him, since he entered into the Order by the hand of his brotherin- law, fra Joan de Vilagut, until he became a confidant of King Joan II and his side took part in Catalan Civil War in the fifteenth century. In parallel, Rocabertí also devoted himself to poetry and wrote at least two pieces, the Estrampa, so far unpublished, here this work is published critically, and La glòria d’amor, a long narrative poem, which is a study of possible chronology. Moreover, also studied other people linked to Bernat Hug, like his brothers, authors of some interesting battle letters, also published for the first time, or their brothers-inlaw, among them Joan de Vilagut, also a poet, and Guillem Tinter, who had a poetic Exchange with Vilagut. The whole work is accompanied by transcription of an interesting collection of documents.

On the way to solve lighting problems in underwater imaging

A major obstacle to processing images of the ocean floor comes from the absorption and scattering effects of the light in the aquatic environment. Due to the absorption of the natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion, and, as the vehicle moves, induce shadows in the scene. For this reason, the first step towards application of standard computer vision techniques to underwater imaging requires dealing first with these lighting problems. This paper analyses and compares existing methodologies to deal with low-contrast, nonuniform illumination in underwater image sequences. The reviewed techniques include: (i) study of the illumination-reflectance model, (ii) local histogram equalization, (iii) homomorphic filtering, and, (iv) subtraction of the illumination field. Several experiments on real data have been conducted to compare the different approaches

El Forment a la Barcelona baixmedieval: preus, mesures i fiscalitat (1283-1345)

A través de l'anàlisi de dos sèries de diferents llibres de comptabilitat de Barcelona, els procedents de la gestió dels molins reals i els redactats per una institució eclesiàstica, la Pia Almoina, vam començar a estudiar el mercat del blat a Barcelona durant l'edat mitjana. Hem analitzat anteriorment el valor de les mesures a Barcelona i, per poder qualificar el preu real del pa, també hem estudiat els diferents processos industrials per fer pa de blat. Després, hem analitzat el conjunt d'impostos que pesaven sobre la comercialització de cereals. A través de l'estudi de l'evolució dels preus, hem tractat de fer una primera aproximació de la primera etapa de la crisi baixmedieval, concretament entre 1283 i 1345, tenint en compte els contrastos amb els treballs ja coneguts sobre la base de les fonts on la noció de quantitat no va ser considerada. Finalment, hem comparat els nostres resultats amb alguns treballs referents a la Corona d'Aragó i el món mediterrani, a fi d'obtenir una idea més precisa de la cronologia de les crisis de subsistència
